PUMP-ENGINE.

SPECIFICATION forming part of Letters Patent No. 511,426, dated December 26, 1893.

Application filed May 13, 1893. Serial No. 474,105. (No model.)

To all whom t may concern:

Be it known that I, LEVI HoLBEN, a citizen of the United States, residing at Sacramento, Sacramento county, State of California, have invented an Improvement in Pump-Engines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of engines especially adapted for operating pumps.

It consists in a steam cylinder, the piston rod of which is directly connected with the pump rod, a valve seat with inlet and exhaust, a valve controlling the inlet and exhaust and connections from the kupper end of the piston rod to the valve for automatically operating it, all ofwhich, together with a novel displacer on the piston rod, I shall hereinafter fully describe and specifically claim.

The object of my invention is to provide a simple, compact and effective engine attachment for a pump, and also to provide for a constant and equal dow of water.

Referring to the accompanying drawings for a more complete explanation of my invention,-Figure l is a vertical section of my pump engine. Fig. 2 is a section through the controlling valve.

A is a pump pipe having the spout a. In the lower end of the pipe may be supposed to be the plunger and valves of an ordinary pump unnecessary herein to show.

B is the pump rod.V

C is a base-plate, or cylinder head, with which is formed an upright cylinder D. Within this, is a piston E, having a rod e which passes down to and isl connected with the pump rod B.

F is a valve seat in the base-plate or cylinder head, having a passage fcommunicating with the cylinder D. It has also a steam inlet G and an exhaust H. Within this seat is tted an oscillating valve I, having a port 't' on one side which controls both the steam inlet and the passage to the cylinder, and a port z" on the other side which controls said passage and the exhaust. To the head ofthe valve is connected a lever J. The valve is fitted upon an axis 112 having a nut i3 whereby the valve may be removed at any time for inspection. u

The piston E has an upwardly extending rod e upon which are adjustably fitted the separated collars e2. Upon this rod and between the collars is seated a lever L against which the collars are adapted to come successively in contact. The'outer end of lever L is connected by a link M with the valve lever J, the connection being an adjustable one by means of a slot j in lever J, whereby the throw of the valve may be regulated, said adjustment being made either way and jerking prevented.' Upon the lower piston rod e is seated a displacer N, made of wood, which plays freely in the upper end of the pump pipe A, and is sufficiently smaller than said pipe to not interfere with the flow of the water, while still displacing a portion of it. It

is fitted to rod e by means of a collar n and The steam will thereupon escape from the cylinder and the weight of the parts will carry them down again. As the displacer enters the top of the pump pipe, it will force the walter out, thereby giving a constant dow, both on the up and' on the down stroke. When the limit ot' the down stroke is nearly reached, the upper collar e2 will strike the 1 lever L, and this will again oscillate the Valve I whereby the exhaust will be shut and the inlet will be opened for a repetition of the up stroke. The stroke can be regulated by moving the lower collar e2 up or down.

There is only one stuffing-box in the device, namely, at the base of the cylinder.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, -is-`4 l. An engine attachment for pumps, consisting-of a cylinder having a'piston with a rod extending from one side and connected directly with the-pumpv rod, and having a second rod extending from its opposite side through the upper end of the cylinder and provided with separated adjustable collars,

said cylinder havinga valve seatwith an opening leading to the cylinder on one side of the piston, and inlet and exhaust passages; a valve adapted to oscillate in said seat with ports controlling said passage and inlet and exhaust, a lever on the stem ot' the valve, a second lever fulcrumed on the cylinder and having its inner end mounted on the upper extending rod between the collars so as to be actuated successively by the latter during the movements of the piston, and a link connection between the outer end of the fulcrumed lever and the valve lever whereby the valve is oscillated, substantially as herein described.

2. An engine attachment for pumps consisting of a cylinder having a piston rod extending frorn one side and connected directly with the pump rod, and having a second rod extending from its opposite side through the upper end of the cylinder, a valve seat having a passage communicating with the cylinder'on one side ofA the piston andaninlet and exhaust, an oscillating valve with ports controlling said inlet and exhaust, a lever 0n the valve and a second lever fulcrumed on the cylinder and having the rod from the piston passing through its inner end, adj ustably secured collars on said upper rod above and below said inner end of the lever for actuating the same, a link connecting the outer end of the lever with the valve lever, and a displacer on the piston rod operating freely in the upper end of the pump pipe, substantially as herein described.

In witness whereof I have hereunto set my hand.

LEVI I-IOLBEN.
